Build failure: unable to download model_quantized.onnx from Hugging Face

### Build failure: unable to download model_quantized.onnx from Hugging Face

**Repository:** dotnet-smartcomponents/smartcomponents

**Environment**
- OS: Windows
- Project: samples/ExampleBlazorApp
- Package: SmartComponents.LocalEmbeddings 0.1.0-preview10145

**Observed behavior**
When running `dotnet build` the build fails while attempting to download a model from Hugging Face. The error indicates the SSL connection could not be established and the transport connection was closed by the remote host.

**Error (excerpt)**
```
Restore complete (0.5s)
ExampleBlazorApp net8.0 failed with 1 error(s) (0.2s)
C:\Users\MPhil\.nuget\packages\smartcomponents.localembeddings\0.1.0-preview10145\build\SmartComponents.LocalEmbeddings.targets(39,9): error MSB3923: Failed to download file "https://huggingface.co/SmartComponents/bge-micro-v2/resolve/72908b7/onnx/model_quantized.onnx".

```

**Steps to reproduce**
1. Clone the repository.
2. Open `samples/ExampleBlazorApp`.
3. Run `dotnet build`.
4. Observe the error shown above during restore/build.

**Hypothesis**
The file `onnx/model_quantized.onnx` at the URL above may have been moved, removed, or the Hugging Face path changed. As a result the build-target that attempts to download the file fails with an SSL/connection error.

**Suggested next steps / possible fixes**
- Verify whether the model exists at the Hugging Face URL and update the URL in the NuGet package/targets if it changed.
- Consider bundling a tested model asset with the package or providing a more reliable host or retry/backoff logic in `SmartComponents.LocalEmbeddings.targets`.
- If the model was intentionally removed, update package documentation and targets to reflect the new location or provide guidance for users to obtain the model manually.

**Additional context**
- Reported by user when building locally on Windows (exact output included above).
